Multi-domain co-browsing utilizing localized state management

ABSTRACT

A master and a slave computing device within a co-browsing session can be identified. The devices can be associated with a first Unified Resource Identifier (URI) where a portion of the URI is a fully qualified domain name of a Domain Name System (DNS) hierarchy. The devices can be associated with a co-browsing application. A request associated with a second URI from the master computing device can be detected. The second URI can share a root domain with the first URI. A portion of a master artifact associated with the master device can be conveyed to the slave device. The master artifact can be associated with state information of the session. A portion of a slave artifact linked to the slave device can be modified with the portion of the master artifact. The devices can be navigated to the second URI in response to the request.

BACKGROUND

The present invention relates to the field of co-browsing and, more particularly, to improving multi-domain co-browsing utilizing localized state management.

Web-based conferencing tools are frequently employed to enhance collaboration between users. One tool which is often utilized is co-browsing, which can permit two or more users to navigate the same networked resource (e.g., Web page) simultaneously within a session. For example, a user can navigate through multiple Web pages on a Web site on one computer while another user views the navigation using another computer. Often times Web sites can span multiple domains such as two sub-domains, which can restrict the use of many co-browsing applications.

Asynchronous Javascript and Extensible Markup Language (AJAX) communication is a commonly used mechanism amongst co-browsing applications. This mechanism is limited, however, by policies of traditional security models. For example, the same origin security policy restricts information exchange between co-browsing applications of different domains. Consequently, often times session information can be lost when co-browsing sessions span multiple domains and/or multiple co-browsing applications.

One current solution utilizes a proxy server as a routing mechanism to each of the domains involved in the co-browsing session. The drawback to this solution is that the proxy server needs to be configured to appropriately route requests to the appropriate domain server hosting the co-browsing application. This configuration can be time consuming and error-prone. Further, frequently the Uniform Resource Identifier (URI) patterns for co-browsing applications have similar patterns which results in URI rewrite rules that can be complex and difficult to maintain. In addition, the ability to share the session information between the co-browsing sessions is not available without exposing the session to security risks. For instance, explicitly configuring session cookies to be more global in nature can allow unauthorized entities access to content of the co-browsing session.

BRIEF SUMMARY

One aspect of the present invention can include a computer program product, a system, an apparatus, and a method for improving multi-domain co-browsing utilizing localized state management. A master and a slave computing device within a co-browsing session can be identified. The devices can be associated with a first Unified Resource Identifier (URI) where a portion of the URI is a fully qualified domain name of a Domain Name System (DNS) hierarchy. The devices can be associated with a co-browsing application. A request associated with a second URI from the master computing device can be detected. The second URI can share a root domain with the first URI. A portion of a master artifact associated with the master device can be conveyed to the slave device. The master artifact can be associated with state information of the session. A portion of a slave artifact linked to the slave device can be modified with the portion of the master artifact. The devices can be navigated to the second URI in response to the request.

Another aspect of the present invention can include a computer program product, a method, an apparatus, and a system for improving multi-domain co-browsing utilizing localized state management. A co-browsing engine can be able to perform co-browsing session state management and/or routing. The co-browsing session can be associated with a shared domain. The shared domain can be two or more networking resources having a common root domain of a Domain Name System hierarchy. The co-browsing session can be associated with a co-browsing application. The co-browsing application can be associated with an interface. The co-browsing engine can reside within a client computing device. A data store can be configured to store a state artifact associated with the co-browsing session. The state artifact can include a session identifier and/or a fully qualified domain name. The state artifact can be replicated to a client computing device in response to a co-browsing session request associated with the shared domain.

Yet another aspect of the present invention can include a computer program product, a system, an apparatus, and a method for improving multi-domain co-browsing utilizing localized state management. A request for a Uniform Resource Locator (URI) associated with a first co-browsing application can be received. The URI can be a fully qualified domain name of a Domain Name System hierarchy. The URI can share a common domain name with a historic URI. The first co-browsing application can be associated with a co-browsing session. The co-browsing session can be associated with a state artifact. The first co-browsing application can be associated with a client computing device. A state information of the state artifact associated with the first co-browsing application can be identified. The state information can be at least one of a session identifier and a domain. The state information of the state artifact can be replicated to a second co-browsing application. The second co-browsing application can be associated with a different computing device.

DETAILED DESCRIPTION

The present disclosure is a solution for improving multi-domain co-browsing utilizing localized state management.

FIG. 1 is a schematic diagram illustrating a method 100 for improving multi-domain co-browsing utilizing localized state management in accordance with an embodiment of the inventive arrangements disclosed herein. Method 100 can be present in the context of system 200 and interface 300. In method 100, a co-browsing session can be established between a master computing device and a slave computing device via a co-browsing application. The master and slave computing device can be client computing devices communicatively linked to a co-browsing server. For example, co-browsing application can be a co-browsing widget executing within a Web browser. The master computing device can be utilized to perform state management to enhance co-browsing sessions interacting with shared domains. That is, the master computing device can perform routing and state management functionality traditionally performed by a proxy server. For example, a co-browsing application state can be persisted by the master computing device when a moderator navigates to a sub-domain from a root domain of a Web site.

As used herein, a master and slave computing device can be a computing device executing a co-browsing application within a computing environment. The co-browsing application can be associated with a co-browsing session. The master computing device can be a computing device able to store state information associated with the co-browsing session. The slave computing device can be a computing device able to receive state information from the master computing device. A co-browsing session can be a joint navigation of a networked resource by two or more computing devices. Co-browsing can include, but is not limited to, joint navigation, screen sharing, desktop sharing, application sharing, a Web conference having co-browsing portions, a text chat associated with co-browsing capabilities, and the like. A networked resource can include, but is not limited to, a Uniform Resource Identifier (URI), a Uniform Resource Locator, and the like. For example, a URI can be a file stored within a server computer addressable by a fully qualified domain name and a file name. Networking resource can include, but is not limited to, a network protocol, a domain name, a networking port, a resource path, a resource name, and the like. For example, a networking resource can be a Web page associated with a Web site (e.g., http://abc.domain.com/home.html).

As used herein, a shared domain can be two or more networking domains sharing a common root domain of a Domain Name System (DNS) hierarchy. The root domain can include an Internet root domain, a network domain, a sub-domain, and the like. For example, the root domain can be a root Internet domain such as www.example.com. Shared domain can include, but is not limited to a URI, URL, Uniform Resource Name, and the like. In one instance, shared domain can include an Internet Protocol address associated with different ports. For example, an IP address can be associated with two networking ports such as port eighty and port ninety. Shared domain can include, but is not limited to, alphanumeric characters, numeric characters, and the like. It should be appreciated that the disclosure is not limited to Internet domains and can be extended to accommodate any namespace system where same origin policies constrain the system.

In step 105, a co-browsing session can be initiated. The co-browsing session can be initiated via one or more traditional and/or proprietary procedures. In one embodiment, the co-browsing session can be initiated via a master computing device. In the embodiment, the master computing device can designate slave computing devices which can join the session. In step 110, a master and slave computing device can be joined to the session. The master and slave computing device can be identified based on permissions, configuration options and the like. For example, a master device can be determined based on a moderator status of a user. In step 115, a domain can be selected by the master computing device. Domain selection can be performed automatically and/or manually. In one instance, domain selection can be an automated Hypertext Transport Protocol (HTTP) redirection to a domain. In another instance, the domain can be selected manually via user input. For example, a user can utilize a human interface device (e.g., keyboard) to input a Uniform Resource Locator (URL).

In step 120, the master and slave computing device can be navigated to the selected domain. Navigation can include, but is not limited to, one or more HTTP requests, content rendering, Asynchronous JavaScript and Extensible Markup Language (AJAX) requests, and the like. In step 125, a shared domain can be selected by the master device. The shared domain can be selected in response to an automatic and/or manual event occurrence. For instance, shared domain selection can be performed when a user selects a hyperlink. In step 130, shared domain navigation can be detected. Detection can be performed via one or more traditional and/or proprietary mechanisms. In one instance, detection can be performed via request interception. In the instance, an HTTP request can be analyzed prior to conveyance to determine when a shared domain is requested.

In step 135, a state artifact of the master computing device can be replicated to the slave device. The state artifact can be one or more entities associated with the state of the co-browsing session. In one instance, a state artifact stored within master computing device can be copied and conveyed to the slave computing device. In the instance, the state artifact can be an HTTP cookie which can be utilized to synchronize the state between the master and slave device. It should be understood that the state artifact can be selectively replicated. That is, state information can be selectively replicated to maintain security policies. In step 140, the master and slave computing device can be navigated to the shared domain. In step 145, the method can end.

Drawings presented herein are for illustrative purposes only and should not be construed to limit the invention in any regard. In method 100, step 115-145 can be performed each time a domain is selected. That is, the method can be continuously executed during a co-browsing session to enable state maintenance across multiple domains. It should be appreciated that method 100 can be applied to any co-browsing session to permit statefulness of the session. For example, the method 100 can be applied to a co-browsing session through the manual activation of a configuration option. It should be understood that method 100 can be utilized in the context of multiple master computing devices, multiple slave computing devices, and the like.

In one embodiment, method 100 can be implemented in the presence of a master and slave computing device change during the course of a session. In the embodiment, as a computing device privilege is elevated and/or restricted, the method can be utilized to maintain session state.
